The fibers may be of different materials like steel, polymer, glass, carbon, or even natural fibers like coconut fiber.
Scientists Have Reinforced Concrete With Plastic Waste
2015/3/1111 MARCH 2015. Researchers from James Cook University in Australia have created a type of concrete that's reinforced by plastic waste, rather than steel. The technique, which is a first in Australia, will greatly reduce the environmental impact of concrete, and we can't help but wonder why we're not doing this already. "Using recycled plastic
